1，获取方法：
- (UIViewController *)activityViewController{
UIViewController* activityViewController = nil;
UIWindow *window = [[UIApplication sharedApplication] keyWindow];
if(window.windowLevel != UIWindowLevelNormal){
NSArray *windows = [[UIApplication sharedApplication] windows];
for(UIWindow *tmpWin in windows){
if(tmpWin.windowLevel == UIWindowLevelNormal)
{
window = tmpWin;
break;
}
}
}
NSArray *viewsArray = [window subviews];
if([viewsArray count] > 0){
UIView *frontView = [viewsArray objectAtIndex:0];
id nextResponder = [frontView nextResponder];
if([nextResponder isKindOfClass:[UIViewController class]]){
activityViewController = nextResponder;
}
else{
activityViewController = window.rootViewController;
}
}
return activityViewController;
}
2，调用方法[self activityViewController];
下面的是我使用的一个例子。
//获取视图控制器，进行网页 即刻刷新
BaseNavController *v = (BaseNavController *)[self activityViewController];
//NSLog(@"%@", v.childViewControllers);
KCTabBarViewController *kc = v.childViewControllers[0];
for (int i = 0; i < kc.childViewControllers.count; i++) {
//NSLog(@"for-- %@" , kc.childViewControllers[i]);
}
ShouKuanViewController *vv = kc.childViewControllers[0];
//NSLog(@"request:%@", request)
